Course overview
A TypeScript course on typing real applications, including React and Node projects. The course teaches the type system as a design tool: modelling domains with unions and discriminated types, narrowing, generics and utility types, then applying it to React components, API boundaries and gradual migration of JavaScript code.
Learners migrate a JavaScript project to TypeScript and type an API client end to end.
Who it is for
- JavaScript developers
- React and Node developers
- Teams adopting TypeScript
- Full stack engineers
Prerequisites
Solid JavaScript knowledge.
How it runs
Learn → Practise → Build → Experience → Demonstrate, ending in a capstone. Delivered by practitioners from the engineering bench, in Madurai, Coimbatore and online.
